RSS24, RSS230
4 Installation and connection
4.1 Installation
The RSS24/RSS230 blowback control is designed for wall-
mounting. At the back of the housing are 4 M6 threaded
bushings for mounting.

4.2 Electrical connections

WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
The leads are run through the PG screw connection at the bot-
tom of the housing.
Wiring and terminal diagrams are included in the appendix.
External solenoid valves must be equipped with contact pro-
tective circuit. On blowback controls complete with sample
gas probe, this protective circuit is already included in the
supplied plug-in connectors for the solenoid valves.
5 Operation and controls
NOTICE
The device must not be operated beyond its specifications.

5.1 Basic operation

Once connected, the blowback control is ready for operation.
The "Power" (Q0) main switch in the front panel switches on
the blowback control. The selector switch (S2) is used to switch
the blowback control from auto mode to manual mode. In
manual mode, the sample gas valve is always on and there is
no automatic blowback. However, the "Manual Puring/
Manual Blowback" (S1) can be used to manually activate blow-
back. Blowback can also be manually activated in auto mode,
for example to clean unexpected contamination of the filter.
A green light indicates when the unit is in auto mode and a
red light indicates manual mode. Both lights are switched in-
ternally by the controller, hence simultaneously serving as op-
eration display for the blowback control.
Note: After switching on the blowback control and when
switching to manual mode, the purging gas valve is activated
first. This forces a cleaning cycle when blowback control is
switched back on following a power failure or accidental shut-
off.

5.2 Setting the time period and blowback

To change the times for the blowback cycle (see timing dia-
gram in the appendix) and the blowback duration, first open
the door to the control box. The blowback control must be
switched on. The times are configured using the buttons on
the control module.
